Best tires for the Ram 1500 — by generation, trim, and use

The Ram 1500 spans four current generations from 2009 to 2026, with OEM tire sizes from 265/70R17 up to 285/45R22. Here is the size-by-year breakdown, the strongest replacement options by use case (highway, all-terrain, towing), and what our data shows on UTQG treadwear and complaint patterns.

The Ram 1500 is the third best-selling vehicle in America after the Ford F-150 and Chevrolet Silverado, and the most under-served of the three when it comes to tire selection guidance. We've already published F-150 and Silverado 1500 guides — this completes the half-ton trio. The Ram's OEM sizes and use cases are close enough to its competitors that the same shortlist of tire models comes up, but the trim-to-size mapping is different, and getting that right is the half of the decision people most often skip.

OEM sizes by generation

The current 5th-generation Ram 1500 (DT, 2019–present) ships with the following OEM sizes depending on trim:

Tradesman, Big Horn (17" wheel): 265/70R17 — load index 113, speed rating T or H depending on year. Highway-biased all-season OEM, typically Bridgestone Dueler H/L Alenza or Goodyear Wrangler SR-A.
Big Horn, Laramie, Lone Star (18" wheel): 275/65R18 — load index 116, speed rating T. Similar all-season highway fitments.
Laramie, Limited, Rebel (20" wheel): 275/55R20 — load index 113, speed rating T. Larger-diameter touring fitment for crew-cab trims.
Rebel (off-road trim): 285/65R18 — slightly taller, often factory-fitted with Goodyear Wrangler DuraTrac (an aggressive all-terrain) or Falken Wildpeak AT.
Limited, Limited Longhorn (22" wheel): 285/45R22 — load index 114, speed rating H. Largest factory size, typically fitted with Pirelli Scorpion Verde or Bridgestone Dueler H/L.

The 4th-generation Ram 1500 (DS, 2009–2018, sold in parallel with the 5th gen as "Ram 1500 Classic" 2019–2024) uses the same 17", 18", and 20" sizes. The 22" was not OEM on the 4th gen.

Best replacements by use case

Highway commuting, family hauling, mostly empty bed: the OEM Bridgestone Dueler H/L Alenza or the Michelin Defender LTX M/S (UTQG 800 — the highest treadwear rating in our truck/SUV dataset). The Defender LTX M/S is the go-to long-mileage choice — owners commonly report 60,000 to 80,000 miles before the wear bars become an issue. The Bridgestone Turanza QuietTrack in LT sizes is the quietest if cabin noise is a priority.

Mixed highway + light off-pavement (gravel, ranch, fishing access): Continental TerrainContact A/T or Michelin Defender LTX M/S in load range E (LT-metric). The TerrainContact A/T is essentially a quiet highway tire with a slightly more aggressive tread that adds gravel and packed-dirt capability without the road-noise penalty of a true all-terrain.

Real all-terrain use (overlanding, two-track, occasional rock): Falken Wildpeak A/T3W or BFGoodrich KO2. Both are 3-peak-mountain-snowflake rated, meaning they're winter-capable as well as off-road capable. The KO2 is the long-time benchmark; the Wildpeak A/T3W has gained share in the past five years on the strength of comparable performance at meaningfully lower price points (verifiable on our TireIndex).

Towing near GVWR (5,000+ lb trailers, fifth-wheel): step up to LT-metric tires with load index 121 or higher. Michelin Defender LTX M/S in LT265/70R17 (load index 121/118 depending on construction) or Bridgestone Dueler A/T Revo 3 LT. Maintain the placard pressure or up to 80 PSI cold per the manufacturer's heavy-load recommendation. See our towing pressure guide.

Winter (Northeast, Midwest, mountain west): a dedicated winter set is the right call for any half-ton truck driven year-round in real winter. Bridgestone Blizzak DM-V2 in the OEM size, or Michelin X-Ice Snow Truck. Both are studless winter tires; the DM-V2 has slightly better ice performance, the X-Ice Snow has slightly better dry-pavement composure for daily-driven trucks.

UTQG and wear data

Our UTQG dataset of 156 tires with verified treadwear ratings shows the following standout long-mileage options in the Ram 1500 OEM sizes:

Michelin Defender LTX M/S — UTQG 800. The highest-rated truck/SUV tire in our data, and the most commonly recommended replacement for half-ton owners who do mostly highway miles.
Continental TerrainContact A/T — UTQG 720. Strong long-mileage option with light-AT capability.
Bridgestone Dueler H/L Alenza Plus — UTQG 720. The OEM successor on many Ram trims.
Goodyear Assurance MaxLife — UTQG 820. The highest UTQG number in our entire dataset, but it's an all-season passenger tire (not strictly truck/SUV) — fits the Ram 1500 in some passenger-metric sizes and is a wear-rate option for owners who don't tow.

NHTSA complaint patterns

Our 80,657 NHTSA tire-related complaints include several Ram-specific clusters. The most common is the OEM Continental ProContact TX fitment on the 22" wheel for 2019–2022 Limited and Longhorn trims — owners report aggressive shoulder wear and cabin vibration well before the published treadwear life. The fix at replacement time is to step away from the OEM Continental and into the Pirelli Scorpion Verde or Michelin Defender LTX M/S in the same size. The pattern is well-known on r/ram_trucks and aligns with the complaint data in our system.

The 2019+ Rebel's factory Goodyear Wrangler DuraTrac is a noisier highway tire than most owners expect — the trade for off-road grip is cabin noise. Falken Wildpeak A/T3W is the most commonly cited quieter replacement in the same off-road category.

Size tools

To verify the exact OEM specification for your year, trim, and wheel size: check the door-jamb placard on the driver's door. Cross-check against the Tirefolio Ram 1500 fitment page for your specific year — we list all OEM and acceptable upsized/downsized options. If you're considering moving to a larger wheel diameter, use our upsize calculator to find OEM-equivalent sizes that don't change overall diameter (and therefore don't affect speedometer reading, transmission shift points, or ABS calibration).

Frequently asked questions

Are 22-inch wheels worth keeping on a Ram 1500?

Largely a styling decision. The 22" platform rides harder and tires cost more per replacement — typically $400+ per tire versus $200–280 for the 18". If you tow or work the truck regularly, the 18" is the more practical wheel. If the truck is a daily driver and styling is part of why you bought it, the 22" is fine — just budget more for tire replacement.

Can I run all-terrain tires on a Laramie trim?

Yes, in the OEM size. Falken Wildpeak A/T3W and BFG KO2 are both available in the 275/65R18 and 275/55R20 Ram 1500 OEM sizes. Expect 1–3 mpg highway fuel economy reduction and slightly more cabin noise compared to a touring tire.

What's the towing-capable load index for a Ram 1500?

OEM P-metric sizes are load index 113 to 116 (per tire ~2,540 to 2,756 lb). For towing near maximum, step up to LT-metric load index 121 (3,297 lb per tire) or higher. The placard inflation is then higher too — typically 60–80 PSI cold.

Do TPMS sensors need to be replaced when I change to LT tires?

The TPMS sensors themselves are wheel-mounted and don't care about the tire metric — they'll work with P-metric or LT-metric tires at any pressure. What may change is the TPMS warning threshold, which is set by the vehicle to alert at 25% below the placard pressure. Higher LT pressures mean the threshold is higher too — Ram's TPMS auto-adjusts but verify the warning light is off after install.

Are winter tires actually worth it on a 4x4 Ram?

Yes, in real winter regions. 4WD helps you accelerate but does not help you brake or corner. A dedicated winter tire set (mounted on a second set of wheels) is the largest single winter-safety improvement available on any vehicle including 4x4 trucks. See the winter tire guide for compound and tread specifics.
